To all whom t may concern;

Be it known that I, FREDERICK Dnssaonn, a citizen of the United States, residing=at Pittsburgh, in the county of Allegheny and 7 State of Pennsylvania; have {invented certain new and useful Improvements in Nut; Locks; of which the following is a specification.

My invention consists of an improvement in nut locks, of theTclass-of'washer locks, and has for its object to provide a cheap,

simple and eflicient means for holding the nut of abolt, and especially in connection with mechanism adapted for useful cooperation with the nut lock itself! I o T Generally stated, the device comprises integral piece of sheet or plate metalppref erably made of a low carbon steelcapable ofbeing easily bent, having a perforated bolt hole, a" bearing portionfor-the nuthaving the function of a washer, a'laterally extended portion adapted to lie flatly against the face ofthe object with. which the bolt and nut are incorporated, and a partially separated lateral tongue or rib portion par.-

tially bent up at one corner and adapted to be bent throughout its entire length at sub; stantially right angles to the extended plate portion for engagement with the side face of the nut. y I

In one formof the construction .the plate is preferably provided with a downwardly extending lip or flange adapted to engage the corner or edge o'rtion of the bolted structure, andthe devlce is made andadapted to operate in the manner as will be more fully hereinafter set forth. Referring to the drawings which trate preferred embodiments ofgthe invention,

The p urpose ofthus bending up the corner portion" of the extendedmember "7 is to provide for the insertion} of a suitable tool as a cold I ch1sel, sw'age,.etc., so that thepartly severed portion 7,may bebent upwardly after wthe nut is screwed tightto a holding posi v tion, as indicated in Figs. 1, 2, 5 and 8, in

which views such part indicated by the numeral 7', [Said portion being cosextensive with the length of the extendedplate'portion 7, and

'ofja length equal to or greater than that of" the WLSllBF'POPtlOH 6, provides a stiff, rigid bracing member for the plate extension,- so

that-when in position, and the partially sevcred rib. or tongue portion'is bent upwardly into holding engagement with the nut, as 0 nut 5 and is of suflicient Width so that when bent-up it -:practically engages the full depth 9 e nut. .7 r

These features are of very considerable advantage in providing against-accidental displacement or Ploosening of the nut lock in service.

the operation of the figures ireferred to,"zthe'washer plate is provided with an edge retaining lip or flange 12. substantially 7 throughout its entire length and of sufficient depth to properly embrace the side edge of 7 member 2, as in Fig. 1-, or of any similar 'OTbJect to which the nut lock is applied.

7 41011185191 this patentmey be obtai d for Such edge flange additionally "braces and strengthens the deviceas an entirety, maintaining'its rigid structure and at "thelsame time also assisting in. holding thelock in position. r a w Y I In the construction shown in Fig.6, the parts are substantially thesame as above described 'and-are'similarly indicated by reference numerals, except that the flange 12 is omitted, adapting the device to application to a continuously flat surface, as in the case of a rail oint or other similar application.

What I claim is:

1. A nut lock consisting of an elongated Washer plate having a longitudinal rearwardly extending flange along one side and a bolt hole at one end, and a partly severed side portion at the other end provided with an outermost turned up corner and an inner locking edge adapted to be turned up at right angles to the washer plate.

2. A nut locking and bracing washer plate having atone end a Washer portion provided With a bolt hole and an extended .portion partly severed therefrom having an inner nut-engaging edge and an outer partly turnedvup corner adapted to be set up at right angles. to the plane of the plate throughout said extended portion to provide a bracing and locking rib, and a holding flange extending throughout the length of the device in an opposite direction from one edge of the plate.

In'testimony whereof I hereunto affix my signature,

FREDERICK DESSAUER.
